• A bstract The B + → Jψη ′ K + decay is observed for the first time using proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9 fb − 1 . The branching fraction of this decay is measured relative to the known branching fraction of the B + → ψ (2 S ) K + decay and found to be B B + → Jψη ′ K + B B + → ψ 2 S K + = 4.91 ± 0.47 ± 0.29 ± 0.07 × 10 − 2 , where the first uncertainty is statistical, the second is systematic and the third is related to external branching fractions. A first look at the J/ψη ′ mass distribution is performed and no signal of intermediate resonances is observed.
